Hyperinsulinemia Provokes Synchronous Increases in Central Inflammation and  -Amyloid in Normal Adults

Abstract

Inflammation has been implicated as a pathogenetic factor in Alzheimer disease, possibly via effects on beta-amyloid (Abeta). Hyperinsulinemia induces inflammation and is a risk factor for Alzheimer disease. Thus, insulin abnormalities may contribute to Alzheimer disease pathophysiology through effects on the inflammatory network.
